Answer:

160 degrees

Step-by-step explanation:

Step 1: A straight line is 180 degrees. So 180 - 100, is 80 degrees. as the opposite angle measurement of the 100 degree.

Step 2: An isosceles triangle has two equal angle measurements, so two of its angles are 80 degrees.

Step 3: All angles in a triangle equal 180 degrees. So add them up (we will call the missing angle, Z) 180 = 80+80+Z. which equals 180= 160+z

Step 4: Solve it. You subtract 160 from both side which comes out to 20 = Z.

Step 5: Now you have the opposite angle of X. Going back to step 1, A straight angle is 180 degrees. 180 - 20 = 160. X = 160 degrees

Mama L [17]

Answer:

Mme Q spent more time answering emails from students by 10 minutes

Step-by-step explanation:

Here we have

Time spent by Mme Q in answering mails on Friday given by

5/6 Hour = 50 minutes and

7/12 Hour = 35 minutes

Total time spent on Friday = 85 Minutes or

5/6 + 7/12 = 17/12 Hours

Time spent by Mme F in answering mails on Friday given by

1/2 Hour = 30 minutes and

3/4 Hour = 45 minutes

Total time spent on Friday by Mme F = 75 Minutes or

1/2 + 3/4 = 5/4 Hours

Therefore, Mme Q spent more time answering emails from students by 85 - 75 = 10 minutes.

Arthur is organising his collection of DVDs .He has 36 altogether. The ratio of comedy films to action to horror is 4:8: 1 How m

sweet-ann [11.9K]

Answer: Because of the total number of DVDs given (36)the number of individual type of DVD are coming in decimals such that

Number of comedy films =11.07

Number of Action films =22.15

and Number of horror films =2.78

I also solved using total number of DVDs as 26 and the results were as follows

Number of comedy films =8

Number of acton films =16

and Number of horror films =2

Step-by-step explanation:

Total number of DVD collection = 36

ratio of the type of DVD =comedy films to action to horror = 4:8: 1

Total ratio =4+8+1 = 13

Number of comedy films = ratio of comedy films/ total ratio x Total DVD collection

= 4/13 x 36= 11,.07 rounded to 11 comedy films

Number of action films = ratio of action films/ total ratio x Total DVD collection

= 8/13 x 36= 22.15 rounded to 22 action films

Number of horror films = ratio of horror films/ total ratio x Total DVD collection

1/13 x 36=2.78 rounded t0 3 Horror movies .

The numbers of each DVD are giving decimal numbers .

Using

Total number of DVD collection as 26.

we have that

Number of comedy films= 4/13 x 26 = 8

Number of action films= 8/13 x 26= 16

Number of Horror films = 1/13 x 26 = 2
